Getting the same thing here.

So it's a meson issue. Who'd have thought…

As mentioned, saving https://gitlab.freedesktop.org/mesa/mesa/-/commit/a5227465c13ae74651a932a82aeae65683f4a063.diff as mesa-userpatches/a5227465c13ae74651a932a82aeae65683f4a063.mymesarevert fixes the build.

@ObserverOfTime
I tired doing what you have said and have meet with some issues.
ln: failed to create symbolic link '/home/corn/src/mesa-git/a5227465c13ae74651a932a82aeae65683f4a063.mymesarevert': File exists
Steps I took:
cd into the mesa-userpatches directory.
next, wget https://gitlab.freedesktop.org/mesa/mesa/-/commit/a5227465c13ae74651a932a82aeae65683f4a063.diff
then, mv a5227465c13ae74651a932a82aeae65683f4a063.diff a5227465c13ae74651a932a82aeae65683f4a063.mymesarevert
after which I inserted a5227465c13ae74651a932a82aeae65683f4a063.mymesarevert to _community_patches in customization.cfg

Are these the steps you took? if not, would you mind sharing the instruction on how to?

Easier to patch meson.build in the PKGBUILD's prepare:

Thank you! That worked!

side notes:
for me it was between line 274 and 278 in PKGBUILD.

You shouldn't add it to _community_patches because it's not a community patch.

Here's a better patch for the PKGBUILD:

Adding -Dmicrosoft-clc=disabled to _additional_meson_flags also works.
